COVID-19 and COVID-19 vaccination experiences and perceptions and their predictors among community members during the COVID-19 pandemic in Ebonyi state, Nigeria: an analytical cross-sectional study

Background COVID-19 is still a disease of global public health importance which requires long term application of control measures as millions of new infections or re-infections and thousands of related deaths still occur worldwide and the risk of an upsurge from new strains of the virus continues to be a threat. The decrease in the use of and non-use of preventive public health measures are among the factors fuelling the disease. The (previous) experiences and perceptions of people regarding the COVID-19 pandemic, COVID-19 vaccination, and the vaccination process are factors that will influence subsequent use of preventive/control measures. We explored the COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions, and their predictors, among the community members in Ebonyi state, Nigeria. Methods We conducted an analytical cross-sectional study between March 12 and May 9, 2022 among all consenting/assenting community members aged 15 years and above in 28 randomly selected geographical clusters. A structured interviewer-administered electronic questionnaire in KoBoCollect installed in android devices was used to collect data which was analysed using descriptive statistics and bivariate and multivariate generalized estimating equations. Results Of the 10,825 community members surveyed: only 31.6% had strong COVID-19 experience and perception, 72.2% had good COVID-19 vaccination expectation and perception, and only 54.2% had positive COVID-19 vaccination process experience and perception. The most important predictors of the extent/level of COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions were level of attitude towards COVID-19 and COVID-19 vaccination and level of knowledge about COVID-19. Other important predictors were marital status, educational level, and main occupation. Conclusions This study’s evidence, including the identified predictors, will inform subsequent policy actions regarding COVID-19 in the strategies to improve the COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions of community members (and their use of preventive/control measures) in Ebonyi state and Nigeria, and other similar contexts. It will also inform future policy actions/strategies regarding similar diseases.

Background
The coronavirus disease 2019 (COVID-19) caused an unprecedented pandemic and has been affecting the lives and livelihood of the world population since 2019 (for the past four years) [1].Even though it has been declared to no longer be a public health emergency of international concern, [2] COVID-19 is still a disease of global public health importance that requires long term application of control measures as millions of new infections or reinfections and thousands of related deaths still occur worldwide and the risk of an upsurge from new strains of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to be a threat [1,3].Although the rate of testing and reporting have decreased (and testing and reporting have ceased in some countries) [1,3], more than 1.1 million COVID-19 cases and 8700 related deaths were confirmed worldwide between 11 December 2023 and 7 January 2024, with more than 3300 cases in Africa [3].
The decrease in the use of and non-use of preventive public health measures, including COVID-19 vaccination, are among the factors fuelling the global threat of the disease [1].Disease risk perception, confidence in vaccination (in terms of safety/side-effects and effectiveness) and the vaccination process (in terms of ease of access and the appeal of the vaccination system) are factors that influence the acceptance of vaccination as a preventive measure against diseases [4].COVID-19 vaccination (and other preventive measures) is one of the strategies for the long-term management and control of the disease [1].The (previous) experiences and perceptions of people regarding the COVID-19 pandemic, COVID-19 vaccination, and the vaccination process are factors that will very likely influence subsequent acceptance/uptake of COVID-19 vaccination.COVID-19 experiences and perceptions would, in addition to influencing the acceptance/uptake of COVID-19 vaccination, [5,6] also influence the subsequent use of other preventive measures in situations of any COVID-19 upsurge from new variants of the virus [7].
Based on our observations during the pandemic, many people in Ebonyi state and Nigeria strongly believed they had gotten COVID-19, or that they knew other persons who had gotten COVID-19, based only on the symptoms they experienced (without laboratory tests).Whether there were confirmatory laboratory tests or not, such belief or perceptions would influence their practices/ behaviours regarding the pandemic.Even in instances of laboratory confirmed cases of COVID-19 and related deaths, the belief or perception that such cases and deaths were actually due to COVID-19 or not would be an important factor that influence healthy behaviours.Such belief or perception is not uncommon in Ebonyi state (and Nigeria/other African countries) where morbidity and mortality related to many common diseases (with known causes based on scientific knowledge) are often being attributed to superstitious causes (such as spiritual attacks).This was perhaps more pronounced during the COVID-19 pandemic, as we observed anecdotally, due to the misinformation, disinformation and conspiracy theories about COVID-19 and COVID-19 vaccination that overwhelmed the conventional and social media.
An understanding of people's COVID-19 experiences and perceptions, and the determinants, would be important in the subsequent planning of tailored COVID-19 behaviour change communication strategies in Ebonyi state and other similar settings.There was therefore the need to assess and explore people's experiences and perceptions of the COVID-19 pandemic and COVID-19 vaccination and the vaccination process in Ebonyi state in order to provide a more complete picture.
We carried out an extensive geographical communitybased study to assess COVID-19 vaccination acceptance and the determinants among the community members in Ebonyi state [8].As part of the study, we also assessed and explored the experiences and perceptions about COVID-19 and COVID-19 vaccination and its processes, and their predictors, among the community members during the pandemic in Ebonyi state, Nigeria, in order to generate evidence to inform subsequent policy actions and interventions regarding the global threats from COVID-19 and other possible outbreaks of similar diseases in the future.

Study design and participants
The study was an analytical cross-sectional survey which was conducted between March 12 and May 9, 2022 among community members in geographical clusters in Ebonyi state, southeast of Nigeria.The study protocol has been described elsewhere [8].Clusters were the immediate catchment communities/villages of primary healthcare (PHC) facilities and eligible clusters were those with 200 or more households, or a population of 1000 or more people, whose PHC facilities were providing basic maternal and child healthcare services including routine childhood immunization, that could be easily accessed with a car, and where the cluster heads gave verbal consents.Eligible community members were those aged 15 years and above who gave verbal consent or assent.Eligible participants were selected by stratified cluster sampling technique.The list of clusters obtained from the Ebonyi State Ministry of Health was used to prepare the list of eligible clusters as the sampling frame.Random samples of 21 and 7 clusters were respectively selected from the rural and urban/semi-urban strata using the "sample" command in Stata.In the selected clusters, all the households were visited and the eligible household members were selected to participate in the survey.A sample size of 28 clusters with 15,032 community members was estimated for the parent study [8] and 28 clusters and 10,825 (72.0%) community members successfully participated in the survey.

Data collection
Data was collected through population-based household survey using a structured interviewer-administered community members questionnaire.The questionnaire design was informed by published data and expert validation and pre-tests were carried out by the research team [8].The questionnaire had several sections including sociodemographic characteristics; COVID-19 experiences and perceptions; basic knowledge of COVID-19; and attitude towards COVID-19 and COVID-19 vaccination.The electronic version of the questionnaire was programmed using the KoBoToolbox software and was pre-tested in non-participating clusters.Trained interviewers administered the electronic questionnaire with KoBoCollect installed in android phones or tablet devices.All eligible household members were interviewed.Completed questionnaires were uploaded daily and reviewed for missing, incoherent, and illogical data.The data management and quality control is described in greater details in the study protocol [8].

Independent factors and outcome measures
The independent factors were sociodemographic characteristics, main and most trusted sources of information about COVID-19, level of knowledge of COVID-19, and level of attitude towards COVID-19 and COVID-19 vaccination.The basic knowledge of COVID-19 was assessed using 44 knowledge items, each scored "1" for correct response and "0" for incorrect response with the highest attainable score of 44 and lowest of zero for each participant.Knowledge score of ≥ 75% of 44 was good knowledge and < 75% was poor knowledge.The attitude towards COVID-19 and COVID-19 vaccination was assessed using 16 attitude items, each on a five-category scale of strongly disagree, disagree, not sure, agree, and strongly agree and scored from "1" to "5" or "5" to "1" as appropriate.For each participant, the highest attainable attitude score was 80 and the lowest was 16.Attitude score of ≥ 75% of 80 was good attitude and < 75% was poor attitude.
The main outcome measures were the extent of COVID-19 experience and perception, level of COVID-19 vaccination expectation and perception, and level of COVID-19 vaccination process experience and perception.These outcomes were measured by using 5-8 questionnaire items to assess the experiences and perceptions of participants about COVID-19 and COVID-19 vaccination and the vaccination process, scoring the five categories of each item from 0 to 4, summing the scores for the 5-8 items related to each outcome for each participant, and grading the total scores on a two-level scale such that scores ≥ 50% of the total versus < 50% were respectively considered to be: strong versus not strong COVID-19 experience and perception; good versus poor COVID-19 vaccination expectation and perception; and positive versus negative COVID-19 vaccination process experience and perception.Greater details are described in the study protocol [8].
"Experience and perception" was explored as particular outcomes/variables because "experience" and "perception" are naturally interrelated and influence each other.For example, in the context of COVID-19, someone who have witnessed a case of COVID-19 in the locality might be more likely to perceive/believe that COVID-19 is real and that it is possible to get infected.Conversely, someone who perceive/believe that COVID-19 is real and that it is possible to get infected, will be more likely to experience (observe facts of ) COVID-19 cases in the locality.In other words, someone who perceive/believe that COVID-19 is not real and that it is not possible to get infected, will be more likely not to experience (not to observe facts of ) COVID-19 cases in the locality because any case of COVID-19 in the locality (base on classical symptoms and or lab tests) can more easily be interpreted to be other diseases or "spiritual attack".
The other outcomes were the COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions which were assessed with the five-category 5-8 questionnaire items and dichotomized into positive and non-positive category variables like: fear of getting COVID-19 (very fearful/a little fearful versus not fearful at all/not fearful/not sure), fear of having severe side-effects from COVID-19 vaccination (not fearful at all/not fearful versus very fearful/a little fearful/not sure), etc.

Statistical analyses
Statistical analyses were done with Stata/SE version 15.1 (Stata Corp, College Station, TX, USA).Data was summarized using descriptive statistics, frequencies with proportions (expressed as percentages) and median with inter-quartile range as appropriate.Inferential statistics were done using population-averaged models to account for clustering and at 2.5% significance level to correct for multiple comparisons.For dichotomous or categorical independent factors, prevalence difference in the outcomes with 97.5% CI and p-values were computed using binomial identity generalized estimating equations (GEE) with an exchangeable correlation matrix and robust standard errors.For continuous independent factors, coefficients in the outcomes with 97.5% CI and p-values were computed using the binomial identity GEE models.All the independent factors were added to the GEE model in the adjusted analyses.For the binomial identity GEE models that failed to achieve convergence, gaussian identity GEE models were used instead [9].

Sociodemographic characteristics
The sociodemographic characteristics of the 10,825 community members who participated in the study are presented in Table 1.The median age of participants (IQR) was 30 years .Majority were females (56.1%), were married (52.8%), had a secondary education (56.2%) were self-employed (54.6%), and were living in rural areas (77.7%) and more of them (41.6%) had usual monthly income of 20,000 Nigerian naira (NGN) or less.

COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions
The COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions of the 10,825 community members who participated in the study are presented in Table 2 Regarding COVID-19 experiences and perceptions, more of the participants were very fearful about getting COVID-19 (25.6%) and had the perception that it was not possible at all for them to get COVID-19 (27.6%).Majority of them were sure they had never gotten COVID-19 (61.4%) and did not know any person who had gotten COVID-19 (90.5%).
Regarding COVID-19 vaccination expectations and perceptions, more of the participants had the perception that it was important for them to receive COVID-19 vaccination (30.2%), were not sure about their level of fear of severe side-effects from COVID-19 vaccination (22.9%), and believed COVID-19 vaccination would give them full protection against COVID-19 (36.3%).Regarding COVID-19 vaccination process experiences and perceptions, majority of the participants said they had heard many times that COVID-19 vaccination was available for them to go and receive (57.0%) and more of them said they did not know any COVID-19 vaccination place/site (41.9%).

Predictors of COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions
Prevalence estimates and crude and adjusted prevalence differences and their respective 97.5% CI and p-values are reported for each dichotomous or polychotomous independent factor while crude and adjusted coefficients are reported for each continuous independent factor (Tables 3, 4 and 5).The crude and adjusted p-values of the overall effect of each polychotomous independent factor are also reported (Tables 3, 4 and 5).

Predictors of dichotomized (positive and non-positive) COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions
These results are presented in the appendix.Regarding COVID-19 experiences and perceptions: 4458 (41.2%) were fearful of getting COVID-19 while 6367 (58.8%) were not fearful/not sure and the predictors of being fearful of getting COVID-19 were good attitude towards COVID-19 and COVID-19 vaccination and decrease in age (appendix p 2). 3698 (34.2%) said it was possible for them to get COVID-19 while 7127 (65.8%) said it was not possible or that they were not sure about it and the predictors of having the perception that it was possible to get COVID-19 were good attitude towards COVID-19 and COVID-19 vaccination, good knowledge about COVID-19, and main occupation (appendix p 4).
Regarding COVID-19 vaccination expectations and perceptions, 5930 (54.8%) said it was important for them to receive COVID-19 vaccination while 4895 (45.2%) said it was not important or that they were not sure about it.The predictors of having the perception that it was important to receive COVID-19 vaccination were good attitude towards COVID-     4 Relatives/friends, health workers, place of work, place of worship etc. 5 Knowledge score of < 75% of the highest attainable score of 44 was poor knowledge and ≥ 75% was good knowledge. 6Attitude score of < 75% of the highest attainable score of 80 was poor attitude and ≥ 75% was good attitude

Discussion
This study assessed and explored the experiences and perceptions about COVID-19 and COVID-19 vaccination and its process, and their predictors, among community members during the COVID-19 pandemic in Ebonyi state, Nigeria.According to the study findings: 31.6% had strong COVID-19 experience and perception and the predictors were good attitude towards COVID- Considering the uniqueness of the above outcome measures explored by the study, we did not identify any relevant studies with comparable outcomes for appropriate comparison of findings.However, the low prevalence (31.6%) of strong COVID-19 experience and perception was consistent with the fact that the pandemic was relatively less severe in Ebonyi state and in Nigeria as fewer COVID-19 cases and related deaths were confirmed compared to many other countries.
The relatively high prevalence (72.2%) of good COVID-19 vaccination expectation and perception despite the misinformation/disinformation and conspiracy theories about COVID-19 and COVID-19 vaccination in the media indicate that this misinformation/disinformation had limited negative effects on people's perceptions about COVID-19 vaccination.A plausible explanation could be that, because this study was conducted in the prevailing context of increased availability and access to actual vaccines, the real experiences and close observations and perceptions of the importance, safety/side-effects, and effectiveness of the vaccination among those who were, or knew others who were, already vaccinated, could have influenced their perceptions about the vaccination despite the misinformation/disinformation.However, further studies, especially qualitative studies, are required to provide more insights.The above explanation implies that the negative effects of COVID-19 and COVID-19 vaccination misinformation/disinformation on people's perceptions about COVID-19 vaccination decreased over the course of the pandemic.This is consistent with the reported evidence that people's trust in COVID-19 information on the social media declined over time during the pandemic [10].This was an important finding because the social media was perhaps the foremost channel for most COVID-19 misinformation/disinformation before such information were further circulated via other traditional/interpersonal channels.Another possible factor that could have contributed to the limited negative effects of misinformation/disinformation was the fact that while the misinformation/disinformation was more in the social media, traditional media such as the radio was the main and most trusted source of information for majority of the community members in the study area (as we have observed during the study).
The prevalence of 54.2% of positive COVID-19 vaccination process experience and perception indicate that in the prevailing context of increased availability and access to COVID-19 vaccination in Ebonyi state, Nigeria, more needed to be done by the government and health care leaders to improve the ease of access and the appeal of the COVID-19 vaccination system.We did not identify relevant studies for comparison, however, the predictors identified by this study highlight factors that should be considered by policy makers/health leaders in the design and implementation of strategies to improve COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions in Ebonyi state, Nigeria and other similar settings.
In our study, 41.2% were fearful of getting COVID-19, 34.2% said it was possible for them to get COVID-19, 41.0% were not fearful of having severe side-effects from COVID-19 vaccination, and 51.6% said COVID-19 vaccination would give them protection against COVID-19.A relatively higher proportion of 50.7% were fearful of getting COVID-19 in a study in Nigeria, [11] however, this study was conducted much earlier during the initial waves of the pandemic (in the later-half of 2020) when there was much uncertainty, confusion, and fear/anxiety and this timing could have accounted for the higher value.Moreover, this other study was only online (unlike our study that was a geographical community-based offline survey among participants in both rural and urban/ semi-urban areas) and difference in socioeconomic status between the participants of both studies could have partly accounted for the contrasting findings.Another study in Nigeria reported only 26.0% who perceived they were at risk of getting COVID-19 [12].This lower value could have resulted from the fact that this study had a relatively lower sample size of 360 across only three LGAs in a state and was conducted in mid-2020 when the awareness of and cases of COVID-19 were much lower in Nigeria.Respectively higher proportions of 56.4% perceived they were at risk (low risk or medium to very high risk) of getting COVID-19, 60.9% were confident that the vaccination was safe, and 59.9% were confident that the vaccination was effective in a study in Tanzania [13].Similarly, higher proportions of 47.5% in a study in the UK, [14] 56.3% in Malaysia, 6 59.6% in Iran, [15] and 89.0% in Hong Kong [16] perceived it was likely for them to get COVID-19.However, a lower proportion of 33.7% in Lebanon [17] were afraid of COVID-19.
Our study identified good attitude towards COVID-19 and COVID-19 vaccination and decrease in age as predictors of being fearful of getting COVID-19 and good attitude towards COVID-19 and COVID-19 vaccination, good knowledge about COVID-19, and main occupation as predictors of having the perception that it was possible to get COVID-19.In comparison, the predictors of fear of COVID-19 in other relevant studies include male in a study in Nigeria, [11] and marital status (married/ divorced versus single) in Lebanon [17].It is worth noting that we did not find gender to be a predictor of being fearful of getting COVID-19 or of having the perception that it was possible to get COVID-19 and this was consistent with findings of studies in Lebanon [17], However, other studies have reported that female gender was a predictor of COVID-19 related fear [18][19][20] and of perceived susceptibility to COVID-19, [20] although, there were great variations regarding this evidence between studies across different continents as the effect of gender on COVID-19 related fear was more pronounced in European studies [18].
The predictors of having confidence in COVID-19 vaccination (not being fearful of severe side-effects and perceiving the vaccination is protective) identified by our study include good attitude towards COVID-19 and COVID-19 vaccination, good knowledge about COVID-19, level of monthly income, being married, educational level, and decrease in age.In comparison, the predictors of having confidence in COVID-19 vaccine were good knowledge of COVID-19 vaccine and rural residence in Tanzania [13].
The reasons for some of the above contrasting findings are not clear but could perhaps be due to contextual differences between the study settings.For example, he lower level of perceived susceptibility/possibility of getting infected with COVID − 19 in our study compared to the UK and Hong Kong studies might be as a result of the lower severity of the pandemic in Ebonyi state/Nigeria compared to these countries because the severity of the pandemic influenced people's COVID-19 risk perception [21].Another reason could be time trends in the perceptions of COVID-19 and COVID-19 vaccination as most of these studies were conducted much earlier than our study and during the initial waves of the pandemic when there was much uncertainty, confusion, fear, and anxiety and when there were no real experiences of the importance, safety/side-effects, and effectiveness of actual COVID-19 vaccines/vaccination. Also, most of these other studies were conducted online (unlike our study that was a geographical community-based offline survey among participants in both rural and urban/semi-urban areas) and difference in socioeconomic status between the participants of our study and these other studies could have partly explained the contrasting findings.
In our study, 73.2% had heard COVID-19 vaccination was available for them to go and receive.In comparison, a higher proportion of 93.8% in a study in Tanzania [22] had heard about COVID-19 vaccines.The lower value in our study was perhaps due to specific nature of our outcome (the awareness that COVID-19 vaccination was available for them to go and receive) which particularly reflect the receipt of the health message that people should go and receive COVID-19 vaccination to protect against COVID-19.In our study, 58.1% knew a COVID-19 vaccination place (the combination of those who knew a very close place, a close place, a far place, and a very far place) and this value is not too different from the 63.9% who knew where to get COVID-19 vaccination in Tanzania [22].The slight difference could be due to contextual factors.
A limitation in this study was reporting bias which is associated with questionnaire-based studies.The outcome measurement involved participants reporting their COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions and, as a result, there could be recall bias because some of these experiences and perceptions were past events.But the bias would be minimal because such experiences and perceptions were largely ongoing.Also, the outcomes were related to COVID-19/COVID-19 vaccination which was a controversial topic due to the misinformation/disinformation and conspiracy theories and, as a result, there was the tendency for some respondents to exaggerate good/ desirable perceptions and underestimate perceptions that were not good/desirable.However, this bias would be minimal because the anonymous and confidential nature of the questionnaire survey were duly explained and emphasized to the respondents.
This study had some strengths.It was a geographicalcommunity based study (not online based) that involved participants in both rural and urban/semi-urban areas of Ebonyi state, Nigeria.Thus, the study findings are more generalisable to the entire state and other states in Nigeria, including other poor resource settings with limited internet access.Also, the outcome measures and the potential covariates were pre-specified as the study was registered prospectively and implemented based on a study protocol which was prospectively submitted to a peer-review journal.

Conclusions
There was low prevalence of strong COVID-19 experience and perception, high prevalence of good COVID-19 vaccination expectation and perception, and moderate level of prevalence of positive COVID-19 vaccination process experience and perception among the community members during the COVID-19 pandemic in Ebonyi state, Nigeria.The most important predictors of the extent/level of COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions were level of attitude towards COVID-19 and COVID-19 vaccination and level of knowledge about COVID-19.Other important predictors were marital status, educational level, and main occupation.This evidence should inform subsequent relevant policy actions and interventions, including behaviour change communication strategies, regarding COVID-19 and COVID-19 vaccination and similar diseases in Ebonyi state, Nigeria, and other similar contexts.Further studies, preferably qualitative, are needed on the factors that influence COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions and particularly on the (positive) effects of people's real experiences and close perceptions of COVID-19 vaccination attributes (importance, safety/ side-effects, effectiveness) on COVID-19 vaccination expectations and perceptions amidst (the negative effects of ) misinformation/disinformation, and conspiracy theories.
